Hi again, so since october 28, I have been trying to install and run an old kernel from before this shutdown problem happened and I am now running 4.4.0-210-generic, for the last week(and I use my laptop every day most of the day), I have had no shutdown problems.
Since this problem occur in newer kernels too, than maybe developers can look to this kernel and see what is different, that might cause the problem. To people who want to use this older kernel, just open synaptics and look first to what you have installed by searching for your kernel version number - do not add linux-image or linux-headers. You should see what is installed and modules. Make a screenshot or write it down, then look for this old kernel the same way and install the items from your list. Wait for it to finish. Then either use Grub customizerI use this as there is a GUI and a lot of options, like having a list of kernels shown on start up) or you can just run sudo update-grub from terminal Restart your machine Edit these instructions to fit your own system, that might be different from mine. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs. Laptop won't shutdown. 16.04 Status in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: This is about a fresh Ubuntu 16.04 install on a new laptop (asus x540sa). After pressing the shutdown button in the start menu; the shutdown procedure starts and in the final splash screen the system just hangs. Tried a second time by pressing Esc once the splash screen showed up and I saw that it reaches the line "Reached target shutdown" and just stops there, no matter how long I leave it there the machine won't turn off. I also tried a Kubuntu 16.04 fresh install on the same machine and it hanged too at the final splash screen where the pulsating logo stopped. Then I tried with Esc only to see the exact same line in the end. The issue seems to affect lately quite many users as shown by the google results of the past month / week or so. I have also tried shutting down from the console with shutdown -and all the parameters after that suggested online- and sudo poweroff but unfortunately they didn't do the trick. The exact same situation occurred. Unmounting the swap as suggested online doesn't work. Also rebooting the system is not working either due to the same issue. So right now the only way for me to poweroff the machine is to press the power button on the keyboard continuously. Reproducible: Always Steps to Reproduce: 1.Install OS 2.Do something, anything or nothing 3.Try to shutdown or reboot Actual Results: The computer is not shutting down: "Reached target shutdown" and hangs there. Expected Results: Powering off the machine. For what it's worth, closing the lid won't suspend the system, but using the menu buttons for suspension will do it.
